Those familiar with DA5 know the ground here tells its own story - London clay that swells in winter, shrinks in summer, and keeps contractors on their toes. Years of working across Bexley have taught us which areas need extra attention, particularly near the old gravel pits around Northumberland Heath. Smart groundwork preparation today prevents costly problems tomorrow, especially with the area's mix of 1930s semis and newer developments.
Modern groundwork goes beyond simply digging and pouring concrete. Ground-penetrating radar helps identify hidden obstacles before breaking ground. Precise laser levelling ensures perfect gradients for drainage. Reinforced concrete specifications match soil conditions and structural loads. Each project begins with thorough site analysis, accounting for everything from tree root zones to neighbouring properties.
Twenty-six years navigating Bexley's planning requirements means fewer surprises and smoother projects. Local building control officers recognise our work meets standards first time, every time.

Basic foundation work starts around £3,500 for small extensions. Full driveway excavation and sub-base installation typically ranges £5,000-£8,000. Complex projects involving underpinning or major drainage can reach £15,000-£25,000, depending on ground conditions.
Absolutely - from Albany Park through to Northumberland Heath, we know every corner of DA5. Regular projects take us to surrounding areas like Sidcup and Bexleyheath too.
Simple foundation pads might be ready in 3-4 days. Typical driveway groundworks need 1-2 weeks including excavation and base installation. Major works involving drainage systems or underpinning could extend to 3-4 weeks.
Every groundworks project carries our decade-long structural guarantee. This covers settlement issues, concrete defects, and drainage failures - comprehensive protection that reflects confidence in our engineering standards.
Definitely. CAT scanning locates buried cables and pipes before excavation begins. Root protection zones get special treatment with permeable surfaces or bridging techniques, preserving established trees while creating stable foundations.
