PREPRUFE® Grout EG 75

Product Description

PREPRUFE® Grout EG 75 is a high performance, solvent free, impermeable epoxy grout for maintaining continuity of PREPRUFE® waterproofing systems at pile heads and similar structural penetrations. The product comprises: a base epoxy resin, an epoxy hardener and graded mineral aggregates. The three components are supplied pre-measured for easy on site mixing at the correct ratio.

Product Advantages

• water resistant adhesion to all products in the PREPRUFE® sheet waterproofing system
• impermeable
• high bond to substrate
• rapid strength gain
• high compressive, flexural and tensile strengths
• fluid consistency
• solvent free
• no segregation or shrinkage
• highly resistant to acids, alkalies, common salts and sulphates
• easy mixing and placing

Applications

•  recommended thickness range 10 mm to 75 mm
•  waterproofing of pileheads and pilecaps
•  waterproofing of structural penetrations through PREPRUFE® sheet waterproofing systems

System Components

To achieve continuity of PREPRUFE® sheet waterproofing systems at pile heads and similar structural penetrations, you will need the following system components.

• BITUTHENE® LM – high performance, liquid membrane
• PREPRUFE® 300R sheet membrane
• PREPRUFE® Tape – for sealing of laps in PREPRUFE® sheet membranes
• ADCOR® 500S – hydro-expansive waterstop for concrete construction joints
• PREPRUFE® Grout CEM 100 (optional) – high performance non shrink cementitious grout for re-profiling pile heads before the application of PREPRUFE® Grout EG 75 (see separate product data sheet)

Application

Surface Preparation:

Concrete substrates should be dry and free from surface contaminants, curing compounds and dust. Remove any friable material and laitance by mechanical means. Remove rust from any reinforcement that will be in contact with the epoxy grout.

Formwork:

Formwork must constructed to be leak-proof as PREPRUFE® Grout EG 75 is fluid when mixed. Seal all joints in formwork with a cartridge of sealant/adhesive. All formwork should be coated with a mineral oil or water based release agent, before the grout is placed.

Mixing and Placing:

Using a clean 25 litre pail, pour component A into the pail, add component B and mix using a clean paddle mixer and slow speed drill (max 400 rpm) for two minutes. Slowly add the full contents of component C, mix continuously, and scrape unmixed material from the side and bottom of pail with a trowel. Mix for a minimum of three minutes or until a flowable homogenous consistency is achieved.Pot life at 45º C is around 30 minutes. Pour the grout from the pail into the forms continuously, if more than 20 litres of grout is required, mix the next unit whilst the first is being poured to enable continuous placement. Finish with a trowel where necessary.

Cleaning:

Tools and equipment can be cleaned with a solvent tool cleaner. Use before the epoxy grout has hardened. Observe all health and safety advice of the cleaning solvent manufacturer.

Re-profiling Grout:

Where the use of cementitious re-profiling grout is necessary, use only PREPRUFE® Grout CEM 100. See separate product data sheet. Do not use other non-shrink cementitious grouts or site batched sand/cement mortars.
