Polymer modified high-strength BS 7533 complaint bedding concrete.
Preparation
All substrates must be suitable to receive the laying course as per current good working practices. All substrates for bonded constructions should be clean and thoroughly sound, free from oils, grease, dust, loose particles, or any other contaminants which may interfere with adhesion.
Mixing
The product is mixed to the desired consistency either from a site silo and continuous mixer or in a suitable site mixer if 25kg bags are used. Add 2.3 - 2.5L of clean water per 25kg bag to achieve the desired semi-dry workability. Do not rewet previously mixed batches.
Priming
To achieve a bond strength as described in BS 7533, the substrate must be primed using Priming Slurry prior to placing High-Strength Bedding Concrete. All paving units must be primed with Priming Slurry promptly prior to placing them into High-Strength Bedding Concrete.
Application
High-Strength Bedding Concrete can be applied in a bed of 10 - 75mm in a single pass. Greater thicknesses can be applied but should be laid wet on wet with each layer being sufficiently compacted prior to laying another pass. When applying another layer to a layer that has cured, it should first be primed with Priming Slurry.
Place the product on the pre-soaked and freshly primed base and spread it to the desired depth. Prime the back of the paving unit and immediately place it in position, using a rubber mallet to bed and level. Bedded areas should be protected from foot traffic for a minimum of 12 hours and from vehicle traffic for a minimum of 24 hours dependent on temperature and site conditions.
