DUROCRET-PENETRATE is a pre-mixed, cement-based mortar,without corrosive ingredients, suitable for indoor and outdoor aplications. It consists of special active chemicals, which in contact with moisture and the present hydroxide of lime, react and form insoluble bonds (crystals). These crystals block the capillary pores and seal the shrinkage cracks inside the concrete, so as to prevent any further water absorption. It offers:
- High compressive and flexural strength
- Abrasion resistance
- Very good strength to the substrate
- Simplification of works
- Continuous protection of the construction from water presence asit remains permanent active.
- Excellent bond strength to concrete, under both positive and negative water pressure.
- Sealing of hair cracks with width up to 0,4 mm, even if they appear afterwards.
- Protection of the construction from corrosion of the reinforcement steel of concrete.
There is no influence on the waterproofing of construction, in case of damaging the concrete surface of DUROCRET-PENETRATE. It does not affect the vapour permeabilty of concrete. It has a simple and low-cost application. It is classified as a CC R3 type mortar, for concrete repairs, according to EN 1504-3.
DUROCRET-PENETRATE combines two actions in one product, repair and waterproofing. It is used for concrete or brickwork repair and patching, groove formation etc. It is suitable for repairs of basements, foundations, manholes, water tanks, sewage tanks, before the application of the brushable sealing slurry AQUAMAT-PENETRATE.
Substrate
The substrate should be clean, free of dust, oily or loose materials etc. Very smooth surfaces should be treated with mild sand blasting or water-blasting, or carefully with chemical wash-up with 15% hydrochloric acid. Water leaks should be plugged with AQUAFIX rapid setting cement. The surface should be dampened, before the application of DUROCRET-PENETRATE.
Application
DUROCRET is added into the exact recommended water quantity, under continuous stirring, until a homogeneous mixture is formed. The material is applied uring a trowel as usual. After the end of application, the final surface must be treated for the next 2-3 days, so as for the waterproofing layer to remain slightly wet and harden properly. Damping of the surface should be done by the time DUROCRET-PENETRATE has started hardening in order to avoid the possibility of damages. Usually 2-3 times water spraying is enough per day. The applied surface should be protected from rain and frost.
