Why It Matters Wednesday: Proper Form Setting in Concrete

When it comes to concrete, what you don’t see is often more important than what you do. Before the first yard of concrete ever hits the ground, proper form setting determines whether your driveway, patio, sidewalk, or heated slab will perform for decades — or start failing within a few seasons.

1. Straight Lines & Clean Edges

Forms are what create the finished shape of your concrete. If they aren’t set square, straight, and braced correctly, you’ll see it forever. Crooked edges, uneven borders, and inconsistent thickness all trace back to poor form work.

2. Proper Pitch & Drainage

In our Pennsylvania climate, drainage is everything. Forms must be set with the correct slope to move water away from foundations, garages, and walkways. Even a small mistake in pitch can cause standing water, ice buildup, or long-term damage.

3. Consistent Thickness = Structural Strength

Forms control slab thickness. If they’re not set and secured properly, thickness can vary — which leads to weak spots, cracking, and premature failure. Whether it’s a driveway supporting vehicles or a heated sidewalk system, thickness matters.

4. Holds Everything in Place

Forms must be staked, braced, and secured tightly to withstand the pressure of wet concrete. If they shift during the pour, your project can end up uneven, out of square, or structurally compromised.

5. Protects Your Investment

Concrete is permanent. You don’t get a second chance to “fix it later” without major cost. Proper form setting ensures your stamped patio patterns line up, your edges are clean, and your slab performs the way it was designed.

At RLW Concrete LLC, we treat form work as the foundation of every successful project — because if the forms aren’t right, nothing else will be.

Concrete 101: Understanding the Concrete Mix – What’s in the Bag?

🧱 Concrete 101: Understanding the Concrete Mix – What’s in the Bag? New to concrete? No problem. Whether you're pouring a slab for a shed or managing a new driveway install, it helps to know what’s actually in a concrete mix—and why it matters. At its core, concrete is a simple recipe: cement , aggregates , and water —but slight changes to that recipe can have a big impact on how your project performs. Let’s break down what goes into a standard mix and what each ingredient can do for your concrete. 🧪 The Basic Ingredients 1. Cement Cement is often confused with concrete, but it’s just one part of the mix. It's the binding agent —when combined with water, it reacts chemically (a process called hydration ) to create a paste that hardens and glues everything together. Most mixes use Portland cement , which is widely available and compatible with a variety of applications. 2. Aggregates ( Sand and Gravel ) Aggregates give concrete its volume and strength. These can ...

Concrete 101: A Brief History of Concrete

Concrete 101: A Brief History of Concrete RLW: The Mixer Minute Concrete is one of the most widely used building materials in the world today—but it’s not a modern invention. Its history stretches back thousands of years, proving just how reliable and versatile it is. Here’s a quick look at concrete through the ages. ✅ 1. The Ancient Origins The earliest forms of concrete date back to ancient civilizations. The Egyptians used a mixture of mud and straw for bricks and later developed a lime and gypsum mortar. But it was the Romans who perfected the use of concrete, mixing volcanic ash with lime and water to create structures that still stand today. ✅ 2. Roman Concrete Marvels The Romans built roads, aqueducts, and massive structures like the Colosseum and the Pantheon dome using concrete. Their formula allowed the material to resist cracking and even grow stronger over time when exposed to seawater. ✅ 3. Concrete Disappears—and Returns After the fall of the Roman Empire, ...
