Vandex Injection Mortar (VIM)
Vandex Injection Mortar is a product specially developed to stop rising damp in old brick and stonework structures, granite boulder walls, etc…
Before application, Vandex Injection Mortar is mixed with water for 3 – 5 minutes to form a slurry. 22 mm diameter holes are then drilled in the masonry at 110 mm centres (alternatively 30 mm holes can be drilled at 160 mm centres). The mixed product is then injected into the holes using a hand caulking gun or grout pump.
Vandex Injection Mortar consists of Portland cement, specially treated quartz sand and a compound of active chemicals. By means of a chemical reaction between reactive salts in the structure, moisture, and the Vandex chemicals, a crystalline growth will take place which will block all pores and fine cracks. This creates a barrier through which moisture cannot pass. The mortar will tend to fill any fine cracks or voids and will set to form a solid plug, this replacing any material removed by the drilling operation.
Modern Damp-Proofing Products
Safeguard’s damp-proofing system combines the power of the patented Dryzone Damp-Proofing Cream with a modern fast-track replastering system. Rising damp treatment and replastering can now be completed in just 24 hours.
Breathable and equally as effective as a sand:cement render, the Dryzone System allows for ordinary plasterboard to be used to cover up damp and salt contaminated walls.
