Ronafix Pre-packed Screed was specified for the refurbishment project at South Court, a Grade II Listed Building owned by Sidney Sussex College which is a part of the University of Cambridge.

Part of the work required re-waterproofing of the first floor terrace. The terrace provides access to student accommodation and waterproofing to the rear of the shop units below.

The client specified Ronafix Pre-packed Screed 6-50mm to be laid to falls to provide drainage to the new terrace construction, which was to be waterproofed with mastic asphalt and finished with a tiled surface, providing protection to the existing structure below.

Ronafix Pre-packed Screed 6-50mm is designed to be laid as a thin bonded screed and has very low permeability, high strength and negligible shrinkage. All components of Ronafix Pre-packed Screed 6-50mm are pre-measured in Ronacrete’s factory, giving assurance to the specifier that the screed will perform as expected.

The concrete deck was primed with Ronacrete Standard Primer before Ronafix Pre-packed Screed 6-50mm was laid to falls on the freshly applied primer. Early application of the asphalt waterproofing was possible because Ronafix Pre-packed Screed 6-50mm dries faster than traditional sand and cement screeds, reducing the delay between application of the screed and waterproofing.
