‘Prewetting’ is the process whereby a building site is watered over a period of approximately 10 days prior to the proposed building being constructed. Engineers state pre-wetting of the site is mandatory where a new structure is proposed to be constructed over a site which had previously been occupied by a building with suspended ground floors (e.g. timber floors, concrete slabs on brick build up, etc) or sites which have had significant amounts of established vegetation or even a single large tree.
SA Construction Prewetting delivers a fixed cost service that removes the stress, concern and confusion out of ensuring the site is prewet in accordance with engineer’s strict requirements. The site is setup with commercial grade sprinklers and timers to ensure an effective and efficient watering of the site.
The site is supervised throughout the process and water usage is monitored to ensure the site is wet enough. A fixed cost service means that there are no costly surprises in the unlikely event a site is required to be watered longer than 10 days. With the expectation that site works commence within 3 days of the pre-wet being completed, communication is established early with the builder and any other contractors responsible for site works to ensure the prewet is finished on time and not too early.
