About this Service
South Benfleet residential areas with clay ground often suffer pooling and tarmac cracking. Converting tarmac to a resin-bound, permeable surface gives a SUDS-compliant finish that lowers flood risk and removes recurring weed and oil-stain problems common in Castle Point streets.
Clay ground in South Benfleet usually requires excavation to design a stable base. Where tarmac is moving or cracked, removal and an MOT Type 1 sub-base compacted to 95% density are standard to prevent freeze-thaw damage. Sound tarmac can accept a mechanically keyed resin overlay with primer, but overlay is only suitable when the substrate shows no ongoing movement. Installed systems aim for permeability near 600mm per hour and use slip-resistant aggregate to improve wet-weather safety. Drainage channels or soakaways may be added to meet local SUDS requirements.
Expect a site survey that itemises removal or overlay options, excavation depth, and drainage work. If deep sub-base deterioration exists, full foundation renewal is the practical requirement to avoid early resin delamination. Timing may affect excavation and compaction quality in wet seasons.
