Epoxy Floor Membranes
These products can be a useful material for providing a membrane to the surface of the floor where an existing membrane has failed or is absent. However, there are a lot of details to address if the installation is to be successful.
Above Ground Floors
1. Skirting must be removed and the wall Damp Proof Course found.
2. The floor surface must be prepared by needle gun, scaffolding or enclosed grit blasting.
3. Stabilise salts. The formation of salt crystals is strong enough to puncture the epoxy coating.
4. Fill voids and cracks with a non shrink mortar.
5. Form a small floor to wall joint with a non shrink mortar.
6. Apply the Epoxy coating with a roller or brush. Normally three coats. Dry sad is cast into the final coat to help key  floor screeds.
Choice of Epoxy
This must be able to be applied on to substrate, giving moisture readings of 90%.
Basement Floors
If using Epoxy coatings to the floor, then it is essential that the floor is suitably reinforced and able to withstand water pressure should it come to bear. Check with a Structural Engineer before proceeding.
Possible Failures
Once cured, Epoxy coatings are brittle. If the substrate cracks then the Epoxy will crack. If salt crsytals form they can break through the Epoxy and ;eave a pin hole so compromising the membrane.
A unique machine designed to remove graffiti, paint and moss/lichen growth from buildings. It is also used to clean paving. It is excellent at removing chewing gum. The basic design is a combination of high water pressure and high temperature.
Maximum operating pressure - 100 bar.
Maximum operating temperature - 150 degrees Celsius.
Crack Repair
One of the most significant points of Storm Water Ingress in solid wall construction are cracks in the render or mortar joints. Even the smallest hairline crack can allow a surprising amount of water ingress.
This may be due to capillary action or differential wind pressure. The following works are not intended to be a repair for structural defects or movement cracks due to subsidence. If the cracks are suitable for repair (subject to survey), we utilise a resin injection system. Once this is set the crack is filled on the face of the wall with a normal external filler.
