Deluxe Rapidpad™ Foundations for Lantera 350/Leonara 350

PLEASE NOTE Photos are an indication of how the system works they don’t show how many Deluxe Rapidpads™ are supplied with any of our Garden Buidlings in particular.
Forget laying a concrete base, go for our Deluxe Rapidpads™ Range!

This Unique Range from Dunster House Ltd (Registered Design, Patent Pending) allows you to choose your foundations to suit your budget and requirements.

Benefits for Deluxe RapidPads:
 

1. Our Deluxe Rapidpad™ system is great value for money when compared to concrete and other alternatives. Especially when you consider the time/cost saved in its quick installation and also the insulating qualities and increased rigidity of the Structurally Insulated Panels that form part of this system.


2. What really saves you time with the Premier and Deluxe RapidPads is how quick they are to get level. They have a central 22mm thick bolt on each Pad which allows the upper metal plate that sits under the bearers to be easily jacked up and down by simply turning the nuts on the bolt. So level the four corners of your building using a 6ft level across the bearers and then just tighten up all the other pads so that they rest under the other bearers, and you’re done. Quick and easy leveling which is typically done in under 10 minutes.


3. When building a foundation our customers want to be able to put something in place quickly and easily. Weighing in at just 6kg each, our Deluxe Rapidpads™ are the lightest adjustable spot foundation available and are easy to put into place and adjust.


4. Save Time, Effort and Skip Hire costs– This system requires very little digging out compared to conventional bases such as concrete or even railway sleepers. Just 450mm x 350mm x 40mm per pad, meaning only a tiny fraction of the cart away compared to older methods.


5. There is a wide range of adjustment on our Deluxe Rapidpads™ with the lowest height being 85mm and the highest being 195mm allowing for 110mm of difference in height over the area where the building is situated, so it can cope with slight slopes and uneven ground. Please note: this cannot cope with steep slopes, see more information on suitable sites below.


6. The pads, metal plates, nuts and bolts within our pad foundations are all made from Galvanised steel so they are built to last a very long time – we guarantee them for 12 years against structural failure from corrosion (Please note that we cannot guarantee against subsidence and ground slip as this is dependent upon your ground conditions).


7. Pea Shingles Included, so you don’t have to co-ordinate deliveries with other suppliers.


8. The Difference between the Premier and the Deluxe RapidPad system is that the Deluxe range uses Structurally Insulated Panels instead of Nogginsto add strength to the floor. The Structural Insulated Panels (SIPS) that we include with the system are made from chemically bonded panels with integrated timber supports and frankly could justify a page or two just telling you how good this one part of the foundation system is. The panels are made from a 10mm MFP board then 50mm double foil backed high density Polyurethane Insulation and then 10mm MFP board. There are 50mm x 35mm wooden battens bonded in between the MFP boards for strength. They give the strength needed to span 1250mm centres between pads and give you an insulated floor as well! For comparison you can take a look at our 25mm thick insulated floor option prices to see how much it would cost to insulate to a level only approx. one third as thick. You can actually still add an insulated floor kit as well if you want a seriously well insulated floor as those insulation kits will sit directly underneath the SIPS panels. As well as being better insulated than the Premier RapidPads the Deluxe RapidPads offer a more rigid floor due to the great strength of the SIPS system. The only downside of the Deluxe system over the Premier RapidPads is that you lose 70mm in internal head height as the SIPS sit in between the bearers and the floor boards and so raise the floor by 70mm.


9. Our Buildings and our RapidPad foundations have been designed alongside each other, which is evident when you assemble the products. We’ve made locating your Deluxe or Premier RapidPads simple by pre-drilling all of the bearers on the ranges of buildings these are offered with to accept the bolts on the Premier and Deluxe RapidPad systems. So you can line up these holes with the bolts and simply slot them together. This makes setting out and assembly easier and quicker.

What’s Included?

The Deluxe RapidPad kit includes all the parts you need to build a foundation for your Dunster House Garden Building as shown in the step by step pictures above. This is: The Heavy Duty Plastic Grids, The Galvanised Metal adjustable Pads, the Pea Shingles and the SIPS and fixings.

What sites is this suitable for?

The Deluxe Rapidpad™ Foundations are designed to work in Medium firmness ground conditions. To give you an idea of the types of pressure exerted on the ground one pad may be required to hold about 200kg of weight when a building has furniture within it and is subject to uneven loads across the pads. This is about the same as two grown men standing on a slab the size of a paving slab (300mm x 400mm) and equates to a force of just over 16Kpa. Typically foundations for larger structures like houses may require 100Kpa which is why the foundations are dug down to consolidated ground. In the case of our foundations simply digging down 30-40mm on a medium firm ground and then tamping with the head of a sledgehammer is perfectly sufficient to hold the building stable.

The Deluxe Rapidpad™ Foundation System will be suitable for most, but not every garden. It is not suitable for areas prone to water logged ground conditions or marsh, peat or recently disturbed ground. If you feel unsure if your ground is suitable for foundations exerting approx. 17Kpa of pressure, please employ a local site surveyor prior to purchasing.

Also not suitable for exposed sites with high wind speeds. This is a product for a typical garden where shelter from the wind is provided by fences, walls, trees or houses for example. Our buildings themselves are also unsuitable for high wind loads in exposed areas in any case.
 
Examples of ground that is and isn’t suitable from a leveling point of view are shown below:

This ground is OK

The above diagram shows ground that is within the range of 85mm to 195mm down from the level of the bearers. You may also notice that the ground in between the first and second pad is almost at the height of the level shown, this is fine as the bottom of the bearers only starts at the line marked level.

This ground is NOT suitable

The above diagram gives an example of ground which is too uneven. In this example the two extreme extents of the pads adjustability are shown to the right (85mm) and left (195mm) of the diagram but the pads in between are too far below the level and if jacked up to 195mm high they would not reach the level.

This ground is OK

The above diagram shows ground which is sloping but the slope is within the range of adjustability that the pads can cope with. Over the entirety of the length of the ground from one end of the building to the other the height on one side is 85mm from the level, and the height on the other side is up to 195mm from the level so the adjustment available with the Deluxe RapidPads™ will be able to cope with this slope.

This ground is NOT suitable

The above diagram shows a slope that is too steep for the Deluxe RapidPad™ foundation system. The distance from the level on one side is 85mm but the height difference between the ground and the level on the other side is too much as it is greater than 195mm.

Each pad allows a maximum of 110mm of adjustment in height, the lowest point is 85mm from the ground and the highest point is 195mm from the ground. Please note this means the overall height of the product will be raised by at least 85mm.
