Bulkheads are generally used for retaining water. Materials for bulkhead may vary as at some places one can use concrete, metal, rocks or wood in order to combat harsh waves of water. People in the coastal areas need bulkheads to preserve their area in order to control the flow of water.
While choosing any bulkhead material, you have to consider about toxins, erosion, longevity, aesthetic, wood boring insects and many such factors. However, now you have much better selection of material as compared to decades ago. Now you can also use vinyl material, which is much better material.
Following are few bulkhead materials that are commonly used.
The initial cost of vinyl material can be a bit higher as compared to many other cheaper materials available for the same purpose. However, if you look at its longevity then it is much longer as compared to all others. Besides that, it is light material and also does not absorb any water. Also, it does not corrode, resists buckling and needs lighter tool during construction. There is no problem of wood boring insects.
If you want natural rustic look then you can prefer to use organic material like wood which is much low in price as compared to vinyl. However, its life may be almost half that of vinyl. Such material is prone to cracking and buckling. If you are going to use it in a location where weather exposure is not so challenging then life of your wooden bulkhead will be much longer.
This can easily adapt in marine environments and with the preservatives and chemicals you can increase its retention level. By using good quality of chemicals and using long lasting impregnation techniques you can use such timbers in very challenging water conditions.
The ocean water is considered to be harshest enemy of bulkheads. People have been using creosote preservatives for more than last 100 years and can easily overcome various corrosive elements of salt water. With such preservatives you can prepare your wooden bulkheads for any kind of aquatic environments are cost-effective methods.
This is another cost-effective option for bulkhead. They are available at 50 per cent cost of vinyl and if installed in proper manner, then it will need very little attention. However, you need to treat it for wood boring insects.
In addition to the above there are few other materials used as bulkhead material, but above materials are more commonly used.
