Ground Screw Site Surveys, Load Testing, Supply & Installation 

Pecasa is your one-stop-shop for all ground screw foundation solutions for home, business & specialist construction & civil engineering projects in London and the UK. For clients and contractors, our integrated service provides a streamlined foundation process from the initial site survey and ground assessment right through to load testing, ground screw supply, installation and installation records. 

That leads us nicely onto Professional Ground Screw Site Surveys & Testing 

The ground conditions between different sites can be quite distinct. The performance and capacity of ground screw foundations can be influenced by factors such as the presence of clay, loose soils, made ground and other ground conditions. 

Reporting — Pecasa carries out professional ground screw site surveys and load testing to ascertain if the planned ground screw system is right for your project. This testing can help inform you about actual ground conditions and the performance of the screw before a full install of your foundation. 

Our services include: 

• Ground screw compression testing 
• Ground screw load testing 
• Test for pull-out & tensile of ground screws 
• Installation torque monitoring 
• Site surveys and ground assessment 
• Test screw installation 
• Recorded test results 
• Ground screw supply and installation 
• Garden rooms testing, SIP buildings, modular buildings and other structures 

Compression Examination & Load Screening for Ground Screw 

Pecasa has special testing equipment for your RADIX ground screws and is able to test them in a controlled manner on site. The sample of equipment places an applied load on the test screw, so that its performance and behavior under load can be measured and recorded. 

Testing can build up, depending on what the project is asking for: 

• Loading capacity of a screwed pile 
• Compression performance 
• Pull-out or tensile resistance 
• Installation torque 
• Proposed ground screw fitment 
• If the foundation design must be adapted 

This can be especially beneficial when engaging with structural engineers, architects, contractors and Building Control. 

General Ground Screw Testing (for Building Control (and) Structural Engineers) 

More and more garden rooms, garden offices, annexes, SIP buildings, modular structures and other lightweight buildings are being built using ground screw foundations. 

For some projects, structural engineer or Building Control may require proof of performance / capacity for the proposed foundation system. Pecasa can assist your architect, structural engineer and Building Control team with the suitable test and installation documentation. 

In accordance with the manner of a structural engineer specifying a particular proof load, testing methodology or acceptance requirement, we can review and conduct tests accordingly! 

Standalone Ground Screw Testing 

This testing service isn’t exclusive to those buying a full foundation package from Pecasa. 

We can supply standalone ground screw testing for: 

• Ground screw installers 
• Garden room companies 
• SIP building installers 
• Modular building companies 
• Builders 
• Architects 
• Structural engineers 
• Property developers 
• Commercial contractors 

If you have your ground screw foundation design, just send over the drawings, site details and structural engineer’s load requirements in hopes that a suitable testing service will be found. 

Complete Ground Screw Foundation Package 

For projects in which a full foundation solution is needed, Pecasa can supply: 

Site Survey → Test → Supply Ground Screw → Install & Installation Record 

By offering this simplified approach, clients and contractors are able to collaborate with an experienced provider from the very first site assessment through to the finished ground screw foundation. 

You’ll be able to prove the foundation solution against project-specific requirements before the complete system goes in by combining testing and installation. 

Suitable Applications 

Ground screw foundations and testing services are applicable to a variety of construction projects, including: 

• Garden rooms 
• Garden offices 
• Annexes 
• SIP buildings 
• Modular buildings 
• Timber-frame buildings 
• Suitable extensions 
• Decking structures 
• Commercial buildings 
• Temporary structures 
• Permanent structures 

Ground screws are ideal depending on the site itself, ground conditions, structural requirements and type of building planned. As such, each project should warrant professional review and appropriate engineering input. 

A More Environmentally Friendly Option to Traditional Concrete Foundations 

For projects where they can be used, ground screws offer a realistic alternative to traditional concrete foundations. By reducing the amount of concrete and excavation involved, ground screw foundations can minimise disruption to the surrounding site. 

Installation can also be significantly quicker than that for traditional foundation types Most importantly, unlike traditional concrete curing periods, the right construction projects can get underway almost immediately following ground screw installation. 

This makes ground screws especially appealing for garden rooms, modular structures, SIP buildings &skipped projects where speed, minimizing disruption on-site and greater efficiency of installation play very significant roles. 

Ground Screw Installation and Tracks 

Once the testing is done and foundation size requirements are determined, Pecasa can provide and install the ground screw system that they need. Installation records can be valuable information for the project team and aid in exercise where relevant communication between installer, contractor, structural engineer and Building Control requirements etc. 

By bringing together site assessment, testing and supply & installation we can deliver a much better aligned foundation process with greater visibility for the client from investigation to completion. 

Ground Screw Load Test Want to know your ground screw bearing capacity? 

Whether you need an individual ground screw tested for your project or a whole ground screw foundation provided, tested and installed Pecasa are here to help. 

You can go over your needs, provide the location of your site and also give project packing as well as structural engineer load requirements. Our team are then able to recommend suitable ground screw testing and installation options for your project.
