What is Max Grout used for?

Max Grout is a non-shrink fluid cementitious grout for filling voids, anchoring bolts and dowels, supporting machinery bases, repairing damaged concrete elements, and sealing cracks and voids in walls, floors, and ceilings.

What strength does it achieve?

Max Grout achieves high early-age and final compressive strength typical of structural grouts - exact MPa values per TDS. R4-rated to EN 1504-3 for structural repair.

How is it mixed and poured?

Mix 25kg powder with 3-3.5L clean water (12-14% by weight) to a fluid pourable consistency. Pour into pre-saturated formwork or anchor hole - the fluid grout flows around all features without needing vibration.

Approximately 2 kg/m² per mm of thickness, or 1.4 kg/m² per mm when sand is added for thicker applications. Calculate project needs based on the void volume to be filled.

Standards compliance?

EN 1504-3 Class R4 Structural. EN 1504-6 compliant for rebar anchoring applications. Chloride-free and non-corrosive to steel - safe for use around embedded reinforcement.

How to Use

Pour by gravity continuously in one direction from one side to the other, 5mm to 40mm per layer, placed within 10 to 15 minutes of mixingRemove weak, damaged or deteriorated concrete down to the structurally sound substrate by mechanical, abrasive or percussion means, sandblasting or high-pressure water jetting
Roughen the edges of the repair perpendicular to the surface to a minimum depth of 1 cm
Remove concrete until the exposed reinforcement is not affected and clean the entire perimeter under the reinforcement
Cover the reinforcement with a minimum thickness of 1 cm of MAXGROUT
Remove rust from the reinforcement using a steel brush, sandblasting, shot blasting or a needle gun
Apply MAXREST PASSIVE rust converter and protector
Wash the surface with pressurised water so it is clean and free of dust, grease and loose particles
Dampen the surface of the substrate until saturated before pouring, but avoid forming puddles
Set small mould supplements around the placing area and provide air vents to let air escape from the space to be filled
Pour MAXGROUT into a clean drum containing part of the clean water, then start mixing to break up any lumps
Mix with a slow speed mixing drill at 400-600 rpm for 3 to 4 minutes, using 3 to 3.5 litres of water per 25kg bag and avoiding air bubbles
For volumes greater than about 0.1 m3 or thickness greater than 4 cm, add 8 kg of DRIZORO SILICA 3050 of 3 to 5 mm size per 25kg bag
Allow the mix to rest for 1 to 2 minutes so any introduced air bubbles can disappear
Place within the following 10 to 15 minutes, pouring by gravity continuously and in one direction from one side to the other
Use a manual vibration element only if needed, avoiding excessive vibration which causes bleeding and air entrapment
Begin curing immediately after placement
Above 25C, or in dry or windy conditions, provide moist curing by fogging or with wet burlap covered with plastic sheeting for the first 24 hours, or use MAXCURE curing compound
Clean all tools and equipment immediately with water after use

Drizoro Max Grout 25kg $154.95

Technical overview

MAXGROUT is a one-component, non-shrink, high-resistance fluid mortar of special cements and well-graded mineral products that is mixed with clean water only. It is poured by gravity to fill voids, bed steel column bases and machinery foundations, anchor bolts and rebar, and to restore structural concrete. It is CE marked and carries Declaration of Performance No. 028.01 as a type CC Class R4 structural repair mortar to EN 1504-3, and it meets the requirements for rebar anchoring to EN 1504-6. Assessment is System 2+, where notified body AENOR 0099 certifies factory production control only. That is a manufacturer declaration against harmonised European standards, not an accredited Australian test certificate. No NATA or CodeMark certificate is held for this product.

Key applications

Restoration of concrete structural elements recovering its original shape and function
Concrete repairs affected by corrosion of reinforcements or defects by pouring concrete into formwork such as columns, beams, retaining walls and piles
Repair of structures damaged by frost, deicing salts and mechanical impacts
Repair of structures subject to dynamic loads
Anchoring of pillars in concrete prefabricated structures
Filling of steel column bases
Beam support in bridges
Anchoring of bolts, cables, etc.
Filling of machinery foundation between concrete and steel plates
Void-filling corrective process and consolidation under concrete slabs

Surface suitability

Concrete (structurally sound, weak or deteriorated material removed, edges roughened perpendicular to the surface to a minimum depth of 1 cm)
Concrete (washed with pressurised water and dampened until saturated before pouring, without puddles)
Cement mortar (minimum 28 days curing time for new concrete and mortar before application)

Do not apply MAXGROUT to structurally weak, painted or burnished surfaces without adhesion, and do not apply to water-repellent substrates, bituminous materials, metal, wood, plaster or paint. Do not use MAXGROUT for levelling and finishing of pavements. Allow at least 28 days curing time for new concrete and mortar before application. The optimum application temperature range is 10C to 25C; do not apply when ambient or application surface temperature is below 5C or if such temperatures are expected within 24 hours after placing, and never on frozen or frosted surfaces. Observe the recommended maximum application thicknesses and volumes, minimum 5mm and maximum 40mm per layer. Do not use more water than the recommended ratio, do not add cement or other unspecified compounds, and do not use remains from previous mixtures. Do not mix using violent mechanical means or high-speed mixers, or prolong mixing excessively. Setting times are measured at 20C; higher temperatures shorten these times and lower temperatures increase them. In the presence of water or soil containing sulphates, sea water or wastewater, use the MAXGROUT ANTISULFAT version, and do not use in contact with pure, acidic or carbonated water. Classified Danger: causes severe skin burns and eye damage, may cause an allergic skin reaction and may cause respiratory irritation. Protective rubber gloves and safety goggles must be used to prepare and apply the mixture.

Why trade professionals choose Drizoro

Drizoro is a Spanish manufacturer of cement based waterproofing and concrete repair products, supplied to the Australian trade through The Waterproofing Shop. The range on this site covers Maxseal Foundation and Maxseal Flex, along with repair mortars, grouts, joint products and mesh, used on concrete and masonry where water has to be held back rather than simply shed. Choosing between the rigid and the flexible grade is the key decision, and it comes down to the substrate, the direction of the water and how much movement the structure is likely to see.
