The Challenge
An environmentally sensitive site. A mature woodland setting required precision placement of foundation screws. A €10,000 euro bond was at stake should any of the trees incur damage. In addition the site engineer needed Foundation Screws Ireland to meet stringent uplift requirements.
The Solution
The on site arborist examined each screw location. Hand excavation was required within a metre of the tree trunks.
Foundation Screws Ireland carried out pull tests on six screws in accordance with EN-1977. Screws were exposed by 300mm to allow for differences in elevation. The screws far exceeded the design requirements.
