Normally Fieldshelters are built to the lowest possible costs. This means that a full concrete plinth or rim is usually excluded due to the cost. If the ground is level, a building can be erected direct upon that but our experience shows that poaching of the ground in the winter is a problem. Therefore we suggest that the best cost effective base is to lay type 1 hardcore to level and sufficient to cover the required width and depth eg a 24' x 12' building (7.2 x 3.6m) would have hardcore 26’ wide x 20’ front (7.8 x 6.0m) to back to give a walkway to the front. Laid to a depth of approximately 4” (100mm) this will not only help level any undulating ground but also lift the building slightly above the ground level and stop poaching of the ground.
In both cases heavy timbers are laid on the ground to support the panels and even out minor variations in level. Steel pins are driven to secure the panels but we would recommend customers to drive in fencing posts at regular intervals and secure the corners to these to provide uplift resistance to the winter storms that now prevail. Towable shelters follow the same principle but the posts supplied with these must be securely driven in at all times when static. Care should also be taken when siting to have the prevailing wind come to the side or rear. However because of their open fronted nature and the variable groundworks, shelters cannot be guaranteed against storm damage.
Fixed Field Shelter (Cromarty 40 x 12)
Following customer requests, we are pleased to offer the COLONSAY - our towable field shelters. Sized to suit several horses and designed to fit through standard field gates with ease, these shelters offer durable protection to all stock, with the ability to be moved with standard 4 x 4 or tractor. The design is ideal for summer / winter grazing paddocks or for farms where field rotation means horses are moved from year to year. The shelters are towed using Galvanised steel runners with integral towing eyes. Rather like a big sledge, it is aimed at movement between and around fields where road travel is not necessary.
For longer distance towing we also offer a bolt on castor wheel for improved ground clearance. The COLONSAY accounts for 95% of our towable sales and is available in a wider range of sizes. In purely practical terms lengths longer than 24' (7.2m) are not easily towable.
Towable Field Shelter (Colonsay, with gates and front gutter)
A four sided shelter provides a 360 degree protection from prevailing weather, giving stock access to all faces. The versatile open fronted shelter could also be used to divide a field into smaller grazing areas, giving protection to four adjacent paddocks in a single unit.
Designed with the most economical use of structural timbers in order to minimise waste, the multi-directional field shelter comes in one size only. The structural timbers and purlins of the quadrant shelter are all pressure treated whilst the OSB lining will need a coat of stain or creosote applied by the customer for full life protection. The building can be erected onto a strip concrete foundation or using heavy bearers or farm sleepers laid on level ground. The principle design feature is a heavy full height central post that is concreted into the ground or fixed using a metpost (depending on ground conditions). The four sides are then run off this posts.
In all cases the field shelter must be additionally secured with a fencepost or similar at each edge of the wing. If being used in a field as the junction of four paddocks, it could be that fence straining posts would act in the same way.
