Types of Tie down Anchor system Depending on the Type of Home
There are different kinds of homes and while those which are built in sites can be very stable, manufactured homes would require a lot more protection and security. With how lightweight these houses are, they need to be secured on the ground, without any chance of having it flown over. To do this, there are two options that can be considered.
- Over-the-top tie-down - best use for older types of homes which can take on and battle against uplift force. The best thing about using this type of system is that it doesn’t affect the appearance of the house in any way. The tie down anchor used in the system is hidden in the metal roof and exterior siding.
- Frame tie-down - can work against both uplift and lateral forces. Also known as the diagonal tie down, this can function well with doublewide homes and homes which are new models. Though most new houses today do not follow the same structure as the old ones with built-in tie down system, they also have better and stronger structure. These houses have frame anchors on the rails.
Different Types of Anchors Used
In using a tie down anchor, there are still several types of anchors to choose from. The anchor to be used will depend on the soil or concrete where the house will be anchored to. Some of the classifications of soil include: clay, organic clay, silty clay, clayey silt, clayey gravel, silty gravel, heavy, heavy sand, sandy gravel, rock or hard pan.
It is by basing through these types of soil and concrete that a tie down anchor should be compatible with so that it could work effectively. Some of the types to consider are:
- Rock anchors - also known as drive anchors, this type of anchor is best used to a rock base. This can be used with steel stakes.
- Auger anchors - also known as screw-in anchors, these are great for both soft and hard soil. It is installed by screwing it to the ground by inserting a bar of metal at the top of the anchor. Bear in mind to never dig a hole when installing this type of anchor.
Devices Needed Together with a Tie down Anchor
- Tension and hook-up device - used for adjusting the tension of the anchor system. This device must be compatible to the anchor and should also be strong enough against third party elements like strong winds.
- Roof protector - normally placed at the edge of the rood under the cable. Also known as roof brackets, they prevent the capable from causing any damage to the roof.
