What is Efflorescence?
Efflorescence is a frequent problem in British Columbia. Efflorescence occurs when heat from the sun brings soluble salts to the surface of porous cement based surfaces. The crystalline deposit of salts, usually white, on unsealed porous surfaces such as brick, concrete masonry, mortar, stucco, and natural stone can be removed and prevented. You will generally find it on walls, floors, retain walls, and other porous surfaces.
Removal
We use a few methods of removal ensuring minimal damage is done to your surfaces. Depending on the age of the efflorescence we may need to blast walnut shells to remove large quantities of efflorescence build up. We then use eco-friendly cleaners to remove the residual amount ensuring your surfaces have been restored. We then recommend a Dynacrete® PIM+ or Dynacrete® PIM+ Type S to help prevent further breakouts.
Prevention & Post-removal Solutions
Envio Pressure Washing offers a commercial grade Permanent Internal Membrane (PIM) which is environmentally friendly, non-toxic, odourless, and non-flammable (it’s so safe you can drink it). PIM will not just help prevent efflorescence but, will permanently protect your concrete, brick and other porous surfaces. Dynacrete® products will prevent efflorescence bleed. On top of that, Dynacrete® products will also help protect your surfaces against elements such as weathering caused by rain, salts, oils and chemicals which wears down concrete surfaces over the years. We are able to apply the Dynacrete® products best suited for your situation on both old and new surfaces. Best of all it’s permanent, it outlasts and outperforms nearly every other sealant currently on the market!
How do Permanent Internal Membranes (PIM) work?
Dynacrete® PIM penetrate below the surface and react chemically with the alkali and lime found in the concrete. The chemical reaction causes a silica gel to form a membrane in the pores of the concrete that hydrates into glass in 72 hours permanently sealing your concrete against further damage.
