Estop EasyProof

Dampness Sealing and Waterproofing Chemical for Concrete and Masonry Substrate.


Estop Easyproof is a one component waterborne dual actions chemical that can achieved both surface and in-depth sealing by film formation and crystallisation.

Manufactured from a blend of Inorganic and Organic Polymers that is UV resistance and provide a long term surface protection.  It contains a mild biocide and it inhibits organic growth without endangering the environment.

On application, a surface film is formed rapidly, sealing off the surface causes the other component to penetrate deeply into the substrate and crystallised, providing in-depth pores sealing. One of its components increases the concrete pH to greater than 10, hence reducing re-bar corrosion. Depending on the quantity applied, while providing rapid protection, the curing process will continue as long as there are active components and moisture presence. To stop ground water intrusion without relieving pressure, Estop EasyProof can be injected into soil behind the substrate. Colloidal particles formed carried by ground water will block all seepage points up to 12 metres from the point of injection.

Application Methods


Remove all loose materials by high pressure jetting. Remove old paint by mechanical means i.e scrapper, wet grit blasting or needle hammer. Stop observable water leakage by using Estop Water Plug. Allow substrate to dry until no free water is observed.

1.     Flood Infusion Treatment (Toilet Leak)

This method without hacking must be carried out by our trained applicator. Refer to Method Statement for further instruction.

2.     Injection Method

Drill a 4 to 10 mm hole through the substrate, about 100mm  below the highest point of leakage. Install a packed nipple. Under low pressure (<14 psi above water pressure) with a hand-pump inject 1 to 3 litres of Estop EasyProof. Check leakage after 12 hours and inject more if necessary. If not, seal the tube permanently with Estocrete WR (Epoxy Resin).


Estop EasyProof will not seal dynamic cracks. Contact with wood may cause colour change.


Clean tools with fresh water immediately after use. Glazed surfaces should be clean immediately on contact with fresh water if its original gloss is to be retained.
