Sawston sits on low-lying ground with chalky soil and clay layers beneath. Both conditions affect how a patio performs over time. Chalk compresses unevenly under load; clay holds water and shifts with freeze-thaw cycles. The survey checks the existing ground, measures the depth needed for a compacted Type 1 sub-base and sets the falls away from the house before any material is chosen. Properties on established residential streets off Babraham Road and Cambridge Road often have older brick elevations where DPC clearance is tight. The installer checks the damp-proof course level during the survey and confirms the finished patio surface sits at least 150 mm below it. Porcelain on a full mortar bed with primer slurry and sandstone with sealed joints are both options; the right choice depends on the garden’s aspect and how the ground drains. Flat village plots give little natural gradient to work with, so the falls must be built into the bedding layer rather than relying on the ground itself. Wet ground after periods of heavy rain can also affect when installation is practical. The survey covers all of this before a price is given, with excavation, sub-base, bedding and paving quoted as separate lines so you can see exactly what each stage costs. ## Questions we get in Sawston ### Will the ground in Sawston need extra preparation before laying a patio? Chalk-heavy soil and clay layers are common in Sawston. Both need a compacted Type 1 sub-base of adequate depth before any bedding or paving is laid. The installer excavates to the depth the ground conditions require, confirmed during the site survey, not estimated beforehand. ### How do you handle drainage on low-lying ground? On flat plots the falls are built into the mortar bed rather than relying on natural ground slope. The installer sets a minimum 1-in-60 fall away from the house. If the ground holds water, a channel drain or soakaway may be specified as part of the quote. ### Which patio finishes suit a flat village plot? Porcelain on a full mortar bed with primer slurry handles freeze-thaw cycles well and needs no sealing. Sandstone suits older brick elevations but requires sealed joints to prevent weed ingress. Block paving on Type 1 is an option where vehicle access is needed. The survey determines which method suits the specific site. ### Can the patio design work well with older brick homes? Yes, but DPC clearance is the critical check. The finished paving surface must sit at least 150 mm below the damp-proof course. This is measured during the survey, and excavation depth is adjusted accordingly before any material or layout is finalised. ## Tell Us About Your Patio Project We schedule a site survey and quote excavation, sub-base, bedding and paving as separate lines, so there are no hidden groundwork costs.
