Deep Pour Grout
Heavy Duty Epoxy Grout (50–300 mm depth)
Ideal for civil engineering applications
This high-performance, two-component, 100% solids epoxy grout is developed for deep-void and large-volume grouting. Unlike most epoxy grouts used for deep pours, it controls heat without added aggregate and fills voids in one continuous pour, saving time and labour while delivering exceptional strength. It complements Megapoxy 206 Ultra, which is ideal for pours between 5 to 50mm.

How to Use
Megapoxy Deep Pour Grout is a two-part, solvent-free, flowable epoxy grout designed for deep and large-volume grouting of industrial machinery and civil engineering applications.
Formulated to control heat without added aggregate, it allows for deep grouting (up to 300 mm) in a single continuous pour, providing heavy-duty performance while reducing installation time and complexity.
It is supplied in conveniently pre-packaged 23 kg kits in the correct mix ratio, with a 60-minute work time and a minimum cure time of 24 hours at 25 °C.
Surface Preparation
Concrete
Concrete surfaces should be free from grease and oil. Then remove surface laitance by mechanical abrasion such as scabbling, grit blasting or grinding. If mechanical preparation is not possible, acid etching may be used (see TDS). After preparation, wash thoroughly and allow to dry for 24 hours. For maximum adhesion, the concrete surface should be surface-dry at the time of application.
Metal
Metal surfaces should be grit blasted to AS 1627.2. If grit blasting isn’t possible, mechanically abrade to clean, bright metal. Then degrease by flooding using an industrial-grade degreaser. Wire brushing alone is not recommended.
Coated Surfaces
Remove all coatings before bonding for superior adhesion. For concrete, flame-clean or mechanically treat with a scutching tool, to remove all traces of paint. Complete by diamond grinding or scabbling. For metals, remove all paint and/or galvanizing using good quality paint stripper, followed by grit blasting or grinding.
Safety and PPE
Megapoxy Deep Pour Grout has low VOC. As with all epoxy resins, please wear appropriate PPE, including eyewear, gloves and clothing.
Mixing
IMPORTANT. Only mix quantities that can be placed within the available working time.
Add the entire contents of Part B into the Part A pail. There is enough space in the Part A container to combine both components.
Using a mechanical mixer, mix at low speed (200–400 rpm) for 3 minutes, making sure to scrape the base and corners of the pail. Avoid up-and-down movement of the mixer.
After 3 minutes, scrape the sides of the pail with a straight-edge tool to remove any unmixed material. Do not use the mixer head to scrape the sides.
Mix for another 2 minutes. If a ring of unmixed Part B remains around the edge of the pail, slightly lift and tilt the mixer (approximately 30°) to change the flow and draw the material into the mix. Thorough mixing is essential to achieve the optimal physical properties.
Megapoxy Deep Pour Grout must be applied immediately after mixing.
In higher temperatures, store in a cool place before use (to maintain usable life). Topping up can be carried out at a later stage if required. Where adhesion isn’t required, formwork surfaces should be coated with Megapoxy Wax or a suitable silicone-based release agent.
Clean-up
Use Megapoxy Thinners to clean mixing and working tools.
Use disposable rubber gloves to protect hands and for proper industrial hygiene.

What grout depths is Megapoxy Deep Pour Grout designed for?
Megapoxy Deep Pour Grout is designed for single pours from 50–300 mm, so deep grout pockets and bases can be filled in one go instead of multiple stages, saving time and labour on deep grouting jobs. Megapoxy Deep Pour Grout can also be used from around 20–50 mm in extreme temperatures and where heat control is critical.
How does Megapoxy Deep Pour Grout compare with other deep pour epoxy grouts?
Most standard and deep‑pour epoxy grouts need staged pours and added aggregate to manage heat, which means more handling, more waiting and more site equipment. Megapoxy Deep Pour Grout controls heat through its formulation, so crews can complete single pours from 50–300 mm with no sand or gravel to source, tip in, clean or store.
What’s the difference between Megapoxy Deep Pour Grout and Megapoxy 206 Ultra?
Megapoxy now offers a pourable epoxy grout for almost any application, matched to depth for easier specification and ordering. Megapoxy 206 Ultra is generally used for grout depths of 5–50 mm, while Megapoxy Deep Pour Grout is used for deeper sections from 50–300 mm, and both products are often used on mixed‑level projects. Megapoxy Deep Pour Grout can also be used from around 20–50 mm in extreme temperatures and where heat control is critical.
Where is Megapoxy Deep Pour Grout typically used?
Megapoxy Deep Pour Grout is used for deep machinery bases and skid plates for pumps, compressors, crushers, mills, generators and turbines in high‑load, high‑vibration environments. It is also used for bridge bearing pads, rail and crane rail systems, pile repairs, truncation pockets and other deep voids, including on hot or demanding sites.
Can Megapoxy Deep Pour Grout be used on hot or demanding sites?
Megapoxy Deep Pour Grout is a low‑exotherm deep‑pour epoxy grout, proven in testing for single pours in large foundations and extreme temperature conditions. Because it controls heat through its formulation instead of relying on added aggregate or staged pours, crews can complete deep pours faster with less handling, so people spend less time working in tough conditions and critical equipment can get back online sooner.
How does Megapoxy Deep Pour Grout save time and labour on site?
Megapoxy Deep Pour Grout replaces two or three staged pours with one continuous pour to full depth, which cuts set‑up time and simplifies planning. With a simple two‑component kit and no loose aggregate, Megapoxy Deep Pour Grout reduces mixing steps, site traffic and clean‑up so crews can move on faster.
What performance and working times does Megapoxy Deep Pour Grout offer?
Megapoxy Deep Pour Grout provides around 60 minutes working time at 25 °C and reaches minimum cure in about 24 hours at 25 °C, supporting steady placement and timely return to service. Megapoxy Deep Pour Grout develops compressive strength around 125 MPa (ASTM C579) with high tensile and flexural strengths and low exotherm, helping maintain alignment and stability at depth over the long term.
What mixing ratio and method are recommended for Megapoxy Deep Pour Grout?
Megapoxy Deep Pour Grout is supplied as pre‑metered 5:1 volume ratio kits, so the entire Part B is added to the Part A pail and mixed without extra measuring, reducing errors and waste. Megapoxy Deep Pour Grout should be mixed mechanically at low speed for the specified time, with sides and base scraped during mixing, to achieve a uniform blend and consistent strength across the pour.
What surface preparation is required before using Megapoxy Deep Pour Grout?
Megapoxy Deep Pour Grout performs best on concrete that is clean, free of grease and laitance, then prepared by scabbling, grit blasting or grinding, or acid etched where mechanical methods are not possible. Steel surfaces for Megapoxy Deep Pour Grout should be taken back to bright metal and degreased, with coatings removed, to maximise bond and reduce the risk of later movement or repairs.
