The main element of your park home and the overall structural integrity of your park home is the chassis that your park home is built on. The chassis will be of steel construction, and similar to that of a Static Caravan Chassis.
Your chassis should be well supported throughout the full length of the chassis, and it is recommended that galvanised tripod jacks are used. It is not recommended that timber or concrete blocks are used, as these could cause the transfer of damp from the concrete base to the chassis and through time will cause the chassis to corrode. This in turn will affect the lifespan of the chassis.
You should regularly inspect the chassis for corrosion, however we do not recommend that you go under the home yourself, but to contact specialist contractors to carryout this inspection, ensuring that your home is well supported and the chassis is free from corrosion. However surface rust is fine.
If you live in area where there is extreme moisture, such as nearby the coast, you should increase the frequency of your inspections, and we would recommend that you have your chassis painted when there is a risk of rust of your chassis.
Also have the supports checked regularly to ensure that they are not corroding, and we would recommend the use of galvanised tripod supports.
There should also be plenty of airflow under your park home, and ideally a continual gap of 15mm to 25mm between the bottom of the drip rail of your park home and the brick skirt. No part of your park home should be touching the brick skirt or this will allow moisture to transfer to your park home.
