What Is Silane/Siloxane DPC Injection Material?
Silane/Siloxane DPC Injection Material is a liquid chemical damp-proof course used to control rising damp caused by capillary moisture in masonry walls. After injection into drilled holes near the base of the wall, the material penetrates the porous masonry and forms a water-repellent chemical barrier that reduces further upward moisture movement.
YURU Premium Silane/Siloxane DPC Injection Material is a single-component system based on reactive polydimethylsiloxanes in emulsion. Its high fluidity and wettability help the material distribute through porous masonry while maintaining the original breathability and appearance of the treated wall.
Important Application Note
This product is specifically designed for capillary rising damp. Moisture caused by plumbing leaks, condensation, rain penetration or lateral groundwater pressure should be diagnosed separately before selecting a DPC injection treatment.

Designed to Control Capillary Rising Damp
A chemical DPC injection system targets moisture that rises through porous masonry by capillary action, helping interrupt the upward movement of water within the wall.
Rising Damp
Moisture rises from the ground through the capillary pores of brick, stone and other porous masonry where an effective damp-proof course is missing or no longer performing as intended.
Salt Efflorescence
Rising moisture can transport soluble salts through masonry, leading to visible salt deposits on wall surfaces and contributing to ongoing deterioration.
Flaking or Damaged Plaster
Persistent dampness and salt movement can contribute to peeling, powdering or flaking plaster in the lower part of affected walls.
Persistent Damp Walls
After the chemical barrier is established, further capillary moisture rise is reduced and the wall can begin to dry naturally over time.
Typical signs do not always mean rising damp
Damp staining, peeling finishes or salt deposits can have different causes. The moisture source should be identified before selecting a chemical DPC injection material.
When Is Chemical DPC Injection Suitable?
Chemical DPC injection is intended for masonry affected by capillary rising damp. Suitability depends on the moisture source, wall construction, masonry type and the ability of the injection material to distribute through the wall section.
| Wall / Moisture Condition | Suitability | Selection Consideration |
|---|---|---|
| Capillary rising damp from ground level | Recommended Application | Designed specifically to form a chemical barrier against upward capillary moisture movement. |
| Missing or ineffective damp-proof course | Suitable for Evaluation | Chemical injection can create a horizontal moisture-control zone within the masonry. |
| Red brick masonry | Suitable | Red brick is included among the treatable masonry materials in the product instructions. |
| Solid / hollow concrete blocks | Suitable | Suitable where the wall construction allows effective injection and material distribution. |
| Stone or rubble masonry | Suitable | Designed for porous mineral masonry including stone-based wall materials. |
| Condensation | Not Primary Solution | Condensation is not caused by capillary rising moisture and requires separate moisture diagnosis. |
| Plumbing leakage | Not Primary Solution | The water source should first be repaired or isolated. |
| Rain penetration | Separate Diagnosis | External water entry should be diagnosed and addressed independently from rising damp. |
| Lateral groundwater pressure | Different Waterproofing Strategy | Lateral water pressure is different from capillary rising damp and may require another waterproofing system. |
Use DPC Injection When
- Moisture is rising from the lower wall zone.
- The wall is constructed from porous masonry.
- A horizontal chemical moisture barrier is required.
- The wall can be safely drilled and injected.
- The moisture source has been identified as rising damp.
Do Not Select DPC Injection Based Only On
- A damp-looking wall.
- Surface mold or discoloration.
- Paint blistering alone.
- Salt deposits without moisture diagnosis.
- Below-grade water pressure or uncontrolled leakage.
Before Selecting DPC Injection, Check:
- Is the moisture concentrated in the lower wall zone?
- Does the pattern suggest upward capillary movement?
- Is the wall made from porous masonry?
- Have plumbing and external water-entry problems been ruled out?
- Can the masonry be safely drilled and injected?

How Does the Chemical DPC Work?
The liquid injection material penetrates porous masonry and develops a water-repellent chemical barrier that helps interrupt further capillary moisture rise.
Injected into the Lower Wall Zone
The liquid material is introduced into drilled holes near the base of the affected wall using pressure injection or gravity feed, depending on the wall condition and application method.
High-Fluidity Penetration
Its high fluidity and wettability help the material spread through porous masonry and reach the wall section surrounding the injection zone.
Hydrophobic Chemical Barrier
The reactive siloxane system develops a water-repellent chemical zone within the masonry, helping reduce the upward movement of moisture caused by capillary action.
Natural Wall Drying
Once the chemical barrier is established, further rising moisture is reduced and the existing damp wall can begin to dry naturally. Drying time varies according to wall thickness, masonry type and existing moisture conditions.
Catalysis Time: Approx. 8–10 Days
The product catalyzes within approximately 8–10 days. This does not mean the entire wall will be dry within 8–10 days; wall drying continues gradually after the chemical barrier develops.

DPC Injection Material Estimated Consumption
Estimate the required DPC injection liquid according to wall thickness before confirming project quantity or bulk purchasing.
Estimated theoretical quantity based on the product data sheet.
Approx. 5 L / m
0.25 L × 20 cm = approximately 5 L of material per linear metre of wall.
Approx. 7.5 L / m
0.25 L × 30 cm = approximately 7.5 L of material per linear metre of wall.
Approx. 10 L / m
0.25 L × 40 cm = approximately 10 L of material per linear metre of wall.
Example Project Calculation
Wall thickness: 30 cm
Wall length: 20 m
Standard packaging: 25 L container
Calculation: 0.25 × 30 × 20 = 150 L
Theoretical material requirement = approximately 6 × 25 L containers
Theoretical Estimate Only
Actual consumption can vary with masonry type, porosity, internal voids, wall thickness and injection method. Irregular, rubble or cavity masonry may require additional material compared with dense and uniform masonry.
Liquid DPC Injection vs DPC Injection Cream
Both liquid and cream-based DPC systems are used in rising damp treatment, but they differ in material form, installation method and how they distribute through masonry. The appropriate system depends on wall construction, porosity, equipment and project requirements.
| Selection Factor | YURU Liquid DPC Injection | DPC Injection Cream |
| Material Form | High-fluidity liquid | Cream / paste-like material |
| Application Method | Pressure injection or gravity feed | Commonly introduced through drilled holes using cartridge or injection equipment |
| Distribution | Designed to absorb and distribute through porous masonry | Designed to disperse from the drilled injection zone |
| Professional Pump Use | Supported | Often not required, depending on system |
| Gravity Application | Supported | Generally not the main application method |
| Masonry Assessment | Porosity and internal voids affect consumption and distribution | Masonry condition also affects product distribution |
| Material Quantity | Calculated according to wall thickness and length | Usually determined by hole size, spacing and manufacturer guidance |
| Best Selection Basis | Wall structure, porosity, injection method and project requirement | Wall structure, application simplicity and product-specific guidance |
Which System Should You Choose?
Don’t select a DPC system only by whether it is liquid or cream. Wall thickness, porosity, cavity structure, internal voids, installer equipment and required distribution should be evaluated first. YURU Premium Silane/Siloxane DPC Injection Material is designed as a high-fluidity liquid system for professional pressure or gravity injection.
High Fluidity
Supports absorption and distribution through porous masonry.
Pressure or Gravity Application
Allows different professional injection approaches according to wall conditions.
Wall-section Distribution
Designed to spread through the treated masonry section rather than remain only around the drilled opening.
Why Does Active Ingredient Content Matter in DPC Injection?
Active ingredient content is an important specification when comparing chemical DPC injection materials, but it should not be used as the only basis for product selection. Chemistry, water-repellent performance, masonry compatibility and application behavior should also be reviewed.
≥85%
One Important Specification — Not the Whole Decision
YURU Premium Silane/Siloxane DPC Injection Material specifies an active ingredient content of ≥85%.
However, active content alone does not describe how a DPC material will perform inside masonry. Buyers should also review the base chemistry, water absorption data, penetration and distribution behavior, suitable masonry types and recommended injection method.
Compare It with Performance Data
Active content should not be evaluated alone. The current YURU product data sheet also specifies a water absorption reduction of ≥97%.
Performance Depends on Masonry Interaction
A DPC injection liquid must also penetrate and distribute through the masonry. High fluidity, wettability, wall porosity and internal void structure influence practical application behavior.
Verify the Data Before Bulk Purchase
Distributors and project buyers should compare active content together with the latest TDS, application instructions, water absorption data and sample evaluation.
What Should Buyers Compare?
When evaluating DPC injection materials, review active ingredient content together with base chemistry, water absorption reduction, masonry compatibility, injection method, technical documentation and sample performance where appropriate.
Important Technical Distinction
“Active ingredient content ≥85%” should not be interpreted as “85% silane.” Product specifications should therefore be compared using the exact terminology stated in the technical documentation.
