EV Charger Foundations<\/h1>\n<\/section>\n\n
\n

When it comes to installing free standing EV charging points. Contractors face a choice between the tried and tested, but time-consuming wet pour concrete foundation; or the fast, efficient, and convenient pre-cast EV charger foundation<\/a>.<\/p>\n<\/section>\n\n

\n

Here we look at the reasons why contractors may choose either one of these solutions and the implications this may have on their EV charger installation projects.<\/p>\n<\/section>\n\n

\n

Wet Pour Concrete EV Charger Foundations<\/strong><\/h2>\n<\/section>\n\n
\n

The most frequently used installation method for a civils contractor is to create a concrete foundation using wet pour concrete.<\/p>\n<\/section>\n\n

\n

This is a tried and tested method, but it comes with challenges that can cause significant delays and generate additional costs.<\/p>\n<\/section>\n\n

\n

There is a need to wait for the concrete to dry before the installation is completed, meaning that contractors need to make a minimum of two site visits to complete the installation which can stretch between 48 hours to a week.<\/p>\n<\/section>\n\n

\n

In winter this delay can be exacerbated by the cold weather preventing the concrete curing, making it harder to manage the installation and related projects.<\/p>\n<\/section>\n\n

\n

Then there are risks around animal and accidental damage, human error and the inconsistent sizing that can come from a wet pour and the wooden shuttering used to contain it.<\/p>\n<\/section>\n\n

\n

Pre-Cast EV Charger Foundations<\/strong><\/h2>\n<\/section>\n\n
\n

The alternative to this is a precast EV charger foundation block that removes the need for wet pour concrete.<\/p>\n<\/section>\n\n

\n

The system is designed to be suitable for same day installation as all that is required is the need to dig the hole, drop in the pre-cast foundation block and then connect the EV charger to the adaptor plate.<\/p>\n<\/section>\n\n

\n

A pre-cast EV charger foundation is designed to be a quick, efficient, and reliable way of installing EV charging points.<\/p>\n<\/section>\n\n

\n

Removing the need to wait for the concrete to dry, makes installations more consistent and easier to plan. The pre-cast base also provides a more consistent finish compared to the wet pour concrete base.<\/p>\n<\/section>\n\n

\n

The adaptor plate can be changed in line with updates to EV charging technology, helping to future-proof the installation and reduce future costs.<\/p>\n<\/section>\n\n

\n

Finally, an increased focus on reducing the carbon footprint of projects the hollow pre-cast block requires the use of less concrete than when a wet pour concrete base is implemented.<\/p>\n<\/section>\n\n

\n

Cost Comparison<\/strong><\/h2>\n<\/section>\n\n
\n

The costs associated with a wet pour concrete foundation are the materials along with the labour to dig the hole and then complete the installation. For the EV blocks there is a fixed cost for the block plus the time for the contractor, who may not need to be a civils contractor to dig the hole.<\/p>\n<\/section>\n\n

\n

In the short term the costs are similar when using a wet pour concrete method to create a charger foundation compared to a pre-cast solution.<\/p>\n<\/section>\n\n

\n

However, the risk of delays, damage and inconsistent finishes mean that the cost advantage can quickly be lost. Particularly if the charger needs to be changed in the future.<\/p>\n<\/section>\n\n

\n

Overview<\/strong><\/h2>\n<\/section>\n\n
\n

With the up-front cost of the base being mitigated by the risk of damage, error or bad weather leading to additional costs the choice is a straightforward choice.<\/p>\n<\/section>\n\n

\n

Contractors have the choice between familiarity (wet pour concrete foundation) or convenience, consistency, and adaptability (Pre-cast foundation)<\/p>\n<\/section>\n\n
