Construction Chemicals Envirosafe One Shot Damp Proof Injection Cream Information

Construction Chemicals Envirosafe One Shot Damp Proof Injection Cream is a highly effective silane/siloxane based cream for installing a chemical damp proof course. It is odour and solvent-free and can be installed with hand-operated equipment.

Construction Chemicals Envirosafe One Shot Damp Proof Injection Cream can be injected from one side of the property therefore unsightly holes or plugs are not visible from the outside.



  • Fast, clean damp proof injection
  • No high-pressure dpc pump required
  • Eliminates the use of electric pumps
  • No odour and low-hazard
  • Precise, measured injection
  • No pump cleaning between jobs
  • BBA Approved

BBA Approval

BBA (British Board of Agrement) certification is recognised throughout the construction industry as a symbol of quality & reassurance. It's a vital ingredient for product manufacturers to elp ensure acceptance with specifiers, building control, local authorities & insurers.

Only products and systems that have passed a series of comprehensive assessments – including laboratory tests, on-site evaluations, quality management checks and inspections of production are awarded an Agrément Certificate.

When making a decision to purchase damp proof cream, ensure that it is BBA approved.



Construction Chemicals Envirosafe One Shot Damp Proof Injection Cream technology is a unique silicone emulsion cream for injection into mortar beds to control rising dampness.   Construction Chemicals Envirosafe One Shot Damp Proof Injection Cream  can be used in all types of masonry without the use of high pressure pumps.

The cream is delivered by hand pressure either by use of a caulking gun, mastic cartridge or a simple displacement pump with injector lance. Once in the substrate, One Shot Injection Cream migrates into the masonry pores and rapidly reverts to a liquid phase. Polysiloxanes are formed in situ and the curing of the damp proof course starts immediately with a final cure within 2-6 weeks depending on the wall thickness.

Construction Chemicals Envirosafe One Shot Damp Proof Injection Cream will perform at least as well as any conventional solvent based injection system against rising damp. The unique cream consistency allows horizontal application techniques without the injection agent running out. This, combined with superior stability in the borehole, ensures the optimal penetration of the active ingredient throughout the substrate. In all cases DPC installation should be carried out in accordance with BS 6576 (1985).


Effective and Safe Protection against Rising Damp

 Highly effective formulation enables long lasting and deep penetration of the mortar bed, creating a horizontal barrier against rising damp.


Universal Use

Construction Chemicals Envirosafe One Shot Damp Proof Injection Cream allows the effective treatment of alkaline and pH neutral building materials as well as acidic substrates.



Construction Chemicals Envirosafe One Shot Damp Proof Injection Cream is ecologically safe and non-hazardous. No solvents to harm the environment, no odours and no bulky containers to dispose of. Classed as non hazardous according to current labelling guidelines (`chip 111`) however silicone resin formulations may cause mild irritation, appropriate safety precautions apply.


Controllable and Consistent Consumption Rate

The controlled installation technique ensures effective treatment and consistent consumption rates. Plastic lined containers ensure total use of the material.


Proven Performance                     

Independent research and test reports have proven its effectiveness.


Health and Safety

Construction Chemicals Envirosafe One Shot Damp Proof Injection Cream contains no solvents and is virtually odour free. This means it can be installed in areas that are sensitive to fire risk or personnel that may be affected by solvent based products. As no electrical equipment is required for installing this product it makes installation for easier and safer. For full health and safety data refer to the Product Safety Data Sheet that comes with the product.


There is no fire risk with  Construction Chemicals Envirosafe One Shot Damp Proof Injection Cream and therefore far safer for operators to install.

How to Use It 

Construction Chemicals Envirosafe One Shot Damp Proof Injection Cream is delivered by hand pressure only (either by using a hand pump or a gun) into a series of holes drilled into the mortar course. From here it migrates rapidly into the masonry pores where the injection cream reverts to a liquid phase and polysiloxanes are formed in situ.
During the curing period a low molecular-weight silane vapour is also produced giving excellent migration through the wall.
Holes should be drilled horizontally in the appropriate mortar bed. 


The depth of the hole for various thicknesses of wall is shown it the chart below i.e a standard 9" thick wall will require 1 Litre of DPC Cream to treat approx 5.68 running metres.
Curing of  Construction Chemicals Envirosafe One Shot Damp Proof Injection Cream cream starts immediately with final curing taking 2-6 weeks.
