Beyem Proof

Beyem Proof

One-component, cement-based, polymer modified mortar for concrete surface protection and waterproofing.

About this product

BEYEM PROOF is a one-component, cement based, polymer modified high strength mortar for concrete surface protection and waterproofing. Formulated with special cements, selected aggregates, organic additives and resins to improve adhesion and waterproofing. Specially suitable for  containing water. Approved for potable water contact. Sea-water and sulphate resistant.

Benefits
  • Modified polymer mortar (PCC).
  • High mechanical strengths. Excellent  adhesion.
  • Waterproof up to 1,2 atm of pressure positive lift.
  • Suitable for pump machines and manual applications.
  • Waterproof and permeable to water vapour. Fast hardening without cracking.
  • Both internal and external use.
  • Sea-water and sulphate resistant.
  • Great plasticity.  
Use

Concrete surface protection according to the MC and RI principles: Moisture Control (MC) by surface coating and Increasing Resistivity (IR) by limiting moisture content. Waterproofing of foundations, basement walls, cellars, concrete slabs, walls, tanks, swimming pools, cellars, planters, lift pits, balconies, terraces, bathrooms, showers… Protection of buildings against water damage. 

Substrates

BEYEM PROOF  is suitable for:

  • Concrete 
  • Cement based substrates
  • Rendering and plastering mortar
  • BEYEM’s concrete repair mortars. 
Preparation of substrates

Concrete must be free from dust, loose material, surface contamination and materials which reduce  bond or prevent suction or wetting  by repair materials. Where necessary, concrete  must be cleaned by sandblasting, high pressure water jetting or other approved mechanical methods that do not cause vibration or impact, to leave a clean and keyed surface.  Absorbent substrates should be previously wetted until they are saturated, preventing waterlogging, and applying the mortar  once the surface has a matt appearance. Smooth, slightly absorbent or very damaged substrates should be treated to obtain a surface with minimum guarantees of roughness and tensile strength. For more information regarding substrate preparation, refer to the recommendations provided in EN 1504-10.

Instructions for use

Mix manually or mechanically BEYEM PROOF with  4,75-5,75 l per bag of clean water until a homogeneous,   and lump-free paste is obtained.  Let the mix stand for 5 minutes before application. Apply a minimum of 2 layers  by spray render or by hand (using a trowel). The first layer should be apply with a little less consistency to saturate the substrate. Apply the second layer while the first coat is still fresh. If the final thickness must  reach 5 mm, three layers of product should be applied. 

Cautions and recommendations
  • Do not apply below 5ºC or above 30ºC.
  • Do not apply when there is risk of frost, rain, strong wind or direct sunlight.
  • Do not add water in excess of the recommended dosage .
  • Waterproofing of substrates that can undergo small movements or with little cracks, must be carry out with BEYEM PROOF FLEXIBLE.
  • Critical areas  as fillen joints between vertical and horizontal  elements must be treated with a dry mortar to minimize the application angle of BEYEM PROOF.
  • Apply preferably on the positive side, that is, on the one that receives the water pressure.
  • Applied on negative side, there are risk of detachment if  water pressure is higher than adhesion of material. 
  • Protect the mortar applied of early dehydration, using suitable  curing methods. The curing operation in humid environment is essential for at least 24 hours after application.
  • Do not apply on gypsum, metal or wood.
  • Mix only sufficient material that can be applied  using available labour and equipment.
  • BEYEM PROOF must cure for a minimum of  3-7 days before receiving mechanical loads.
  • Water pressure loadable after 7-14 days.
  • Suitable for potable  water  contact after 28 days and two washes.
