Step 1


Your complimentary consultation and site review helps us understand the specifics of your needs and how best to construct a seawall on your property.

Step 2

Site Plans

After our review, we create your custom site plan. This (and the estimate) gets reviewed with you by one of our experts to agree on specifications.

Step 3


We identify any financing needs and recommend a source, then both parties sign the contract. After a few simple permitting forms get signed, our team gets going.

Step 4


Once we are all systems go, our permitting teams starts the permitting process. This can take anywhere from two to four weeks depending on several factors.

Step 5


With a permit in hand, our barge, concrete, and cap crews can get to work doing what they do best – expert seawall repair and construction for our customers.

Step 6


Before we wrap up, both you and the local permitting authorities have to double check the work and sign off to ensure the job is 100% complete to satisfaction.

Concrete Precast

Concrete Seawalls

Concrete is a go-to for seawall construction. Because it’s more reliable and structurally sound than other previously used construction materials, it’s a strong choice for protecting your property. We pour our concrete seawall panels in our dedicated facility. Then, they are installed on your property in addition to the standard on-site work of pouring, caps, and finishing.

Concrete and Panels Made In-House

WB Williamson Bros. is one of the only seawall contractors to make our own precast concrete panels. We even mix our concrete on-site. Our concrete is regularly tested by independent laboratories to ensure high-grade, top-quality products for your next seawall. 

Our internal team works hard to pour seawall panels to meet the increased demand and prepare the high-quality panels you need to ensure your seawall will last. That’s why we offer a limited lifetime warranty on all of our seawall construction.
