Surface applied, cement based slurry that penetrates into concrete for an in-depth waterproofing trough internal crystallisation; protection against salt water, waste water, chemical products, … Mix with water and apply on concrete like a coating by brush, spraying machine or dry shake applied.


Cristalproof L1 is a unique chemical treatment designed to waterproof and protect concrete from water penetration of pores and capillaries. It is designed to be a surface applied treatment that penetrates into concrete for an in-depth waterproofing solution. Cristalproof L1 actually works within the concrete's substrate to force a reaction between un-hydrated cement particles and water to cause further hydration within the concrete's mass. This results in further hydration within the already established pores and capillaries effectively reducing the permeability of the concrete until water penetration is stopped. In doing so it will make the concrete permanently waterproof. Due to the catalytic nature of this technology, any water penetration that occurs at a later date is again utilized to produce more crystals within the pores and capillaries. This process of increasing concrete's own natural abilities by using Cristalproof L1 means the self healing process of the concrete is in excess of the concrete's normal and natural abilities. It allows concrete to increase the natural autogenously healing process allowing for self-healing capabilities of cracks up to 0.2mm in diameter when moisture is present.

*Recommended use:

.Swimming pools
.Tunnels and subway systems
.Parking garages
.All below grade concrete foundations
.Dry vaults
.Sewage and water treatment plants
.Water towers and water reservoirs
.Marine structures
.Bridge decks
.Concrete walls and floors

*Features,benefits and advantages:

.Virtually eliminates water penetration through concrete
.Will work to prevent high hydrostatic pressure
.User Friendly – simply mix with the appropriate amount of water and brush on
.Will self-heal new hairline cracks to effectively stop water penetration into the  concrete

.Low application cost
.Lowers overall costs through increased life span
.Completely eliminates the need for alternative waterproofing systems
.Lower maintenance costs and increased effective life

.Less volume to accomplish even greater productivity
.Stops corrosion of reinforcing steel, stops penetration of waterborne contaminants resulting in increased durability and reduction of opportunity  costs
.Less chance of error, and no impediment to productivity
.Can be used to stop water penetration through concrete under dramatic conditions
.Eliminates expensive repairs while providing increased durability

*Operational data:

Mixing ratio:8 liter water for 25 kg of CRISTALPROOF L1. Cristalproof L1 can be applied as a brush on slurry:
.two coats of 0,8 kg powder per m2

Cristalproof L1 may also be spray applied:
.one layer of 1,5 à 2 mm thickness

Cristalproof L1 may also be dry shake applied. To do so simply apply the powder spreading it evenly throughout the surface at a rate of 1,5 kg per m2 before power trowelling the application. This system may only be done successfully when a power trowel is used for finishing.

Do not add water to the mix should signs of setting occur!
