Mapei Planigrout 310 – High-Strength Rapid-Hardening Epoxy Grout

96.1kg three-component epoxy grout for machinery foundations, structural anchoring and heavy-duty industrial grouting applications.

Mapei Planigrout 310 is a three-component, free-flowing, rapid-hardening epoxy grout developed for anchoring, repairing and grouting structures, including applications subjected to heavy mechanical loads and vibration.

Formulated from epoxy resin and selected aggregates, Planigrout 310 provides excellent adhesion to concrete and steel, high mechanical strength and resistance to water, oil and chemical attack. Its highly fluid consistency allows it to flow into confined spaces beneath machinery bases and structural support plates.

Planigrout 310 incorporates Mapei Low Dust technology, which considerably reduces dust generated during mixing compared with conventional cementitious-based products. It can be applied in layers between 25mm and 100mm thick, with rapid hardening helping to reduce industrial machinery and equipment downtime.

Mixing Instructions

Planigrout 310 is supplied as a complete three-component kit. All three components must be mixed in the specified proportions to achieve the correct performance.

1. Mix components A and B: Pour all of component B into component A and mix using a low-speed drill with a suitable mixing paddle until uniform. Avoid entraining air.
2. Prepare component C: Place a small amount of the aggregate from component C into a mortar mixer.
3. Add the resin mixture: Gradually pour the mixed components A and B into the aggregate while mixing.
4. Add the remaining aggregate: Add the rest of component C, supplied as four 21kg bags.
5. Complete mixing: Continue mixing for approximately 3–4 minutes until a uniform, lump-free consistency is achieved.
6. Apply immediately: Pour the mixed grout as soon as possible after preparation and complete application within its working time.

Application Guidance

Substrate Preparation

Concrete substrates must be sound, clean and dry. Remove loose material, cement laitance, efflorescence, form-release agents and dust before application. Metal surfaces should be free from dust, loose material, paint, grease and oil. Mapei recommends abrasive blasting to a bare metal finish where appropriate.

Concrete structures cast in situ should be allowed to cure for at least four weeks before applying Planigrout 310.

Pouring and Application

Apply Planigrout 310 by pouring it in a continuous flow into tightly sealed formwork. Application must be completed immediately after mixing, within the available working time.

For large or confined areas beneath machinery support bases, ensure adequate flow and provide air escape routes so the grout can fill the space evenly. A suitable mortar pump may be used where required.

Important Application Limitations

• Do not apply to wet, dirty or crumbling surfaces.
• Do not apply below +10°C or above +35°C.
• Do not use in layers thinner than 25mm or thicker than 100mm.
• Do not use for elastic joints or joints subject to movement.
• Do not use for construction joints between old and fresh concrete.
• Do not thin with water or solvents.
• Do not mix partial kits unless components are accurately weighed using high-precision electronic scales.
• Protect unopened packs from direct sunlight before use.
• Apply immediately after mixing because the chemical reaction generates heat.
