How to Use

Pour by gravity into the dampened drill hole, work the bolt up and down to release air, then fill continuously and slightly overfillDrill the hole with an electrical drill to the diameter and depth required, generally about three times the bolt diameter in diameter and about five times the bolt diameter in depth
Make a dovetail-shaped hole, a diameter bigger in the bottom, to provide a good mechanical key
Where the concrete is not sufficiently sound or of doubtful strength, increase both the hole diameter and depth
Check the hole is large enough for the head of the bolt and its washers, and that the mortar can flow between the washer and the wall of the drill hole
Confirm the drill hole is structurally sound, clean and free from grease, gypsum, loose concrete or any other material that could affect adhesion
Clean the cavity of loose particles and dust with a blow pump, vacuum means, compressed air or water, starting from the bottom of the hole
Dampen the surface with clean water using a swab so it is saturated surface dry, avoiding any free-standing water
Clean all steel and metal elements thoroughly, free of grease, rust and dust
Mix only the amount of material that can be placed in the next five minutes
Mix 3.75 to 4.25 litres of clean water per 25 kg of MAXGRIP manually with a trowel or spatula in a small plastic bowl until the batter is homogeneous and lump free
In hot or windy conditions use cold water to slow the set; use warm or hot water to shorten it
Place the anchor bolts with washers into the drill hole and pour a little MAXGRIP by gravity directly from the mixing container
Work the bolt up and down a few times to eliminate air bubbles
Fill the balance of the drill hole by pouring MAXGRIP in a continuous way, slightly overfilling to avoid ponding of water
Allow 60 to 90 minutes at 20C before placing the nut, and longer if the element is heavy or will be subjected to heavy loads
Keep the element or anchor immobilised during the first few hours until the mortar has achieved a suitable mechanical strength
Clean all tools and equipment immediately with water after use

Technical overview

MAXGRIP is a one-component, quick-setting, shrinkage-compensated fluid mortar of special cements, selected additives and aggregates, designed for use as a rapid anchoring grout in placing and fixing elements in horizontal concrete or masonry. It is mixed with clean water only, sets in 15 minutes at 20C and the nut can be placed after 60 to 90 minutes. Compressive strength runs 14.3 MPa at 90 minutes to 55.1 MPa at 28 days. Drizoro states it must not be used for structural concrete repair, levelling or floor repair. No accredited test certificate and no CE Declaration of Performance are published for MAXGRIP; the figures above are the manufacturer's own values from Technical Bulletin 11.02.

Key applications

Anchoring of foundation plates and construction elements
Anchoring of heavy machinery, small machines and motors
Fixing of safety rails, hand rails and balustrades
Fixing of signs, posts, parking meters and park seats
Fixing of bolts, hooks, pulleys and fences

Surface suitability

Horizontal concrete (drill hole structurally sound, clean and free from grease, gypsum, loose concrete or any other material that could affect adhesion)
Horizontal concrete (cavity cleaned of loose particles and dust with blow pump, vacuum, compressed air or water, starting from the bottom of the hole)
Masonry (surface dampened with clean water using a swab to saturated surface dry, avoiding any free-standing water)
Steel and metal elements to be anchored (thoroughly cleaned and free of grease, rust and dust)

MAXGRIP is designed for anchoring and fixing elements in horizontal concrete or masonry. Do not use it for structural concrete repair, levelling or floor repair; use another Drizoro product for those applications. Do not use more water for mixing than the ratio recommended and do not mix MAXGRIP with other compounds. MAXGRIP sets very quickly, so mix only the amount of material that can be placed in the next five minutes, and do not retemper or extend placement after 10 minutes. Do not apply when ambient or application surface temperature is below 5C or if such temperatures are expected within the 8 hours after placing, and do not apply on frozen or frosted surfaces. Do not add anti-freeze admixtures to the mixing water. Setting times are measured at 20C; lower temperatures and higher relative humidity increase these figures. Allow more curing time if the element to be anchored is heavy or is going to be subjected to heavy loads, and keep the element or anchor immobilised during the first few hours until the mortar has achieved a suitable mechanical strength. MAXGRIP is an abrasive product, so 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.
