Understanding Crazy Paving

The term ‘crazy paving’ might sound a bit eccentric, but it perfectly encapsulates the whimsical charm of this technique. Crazy paving refers to the practice of arranging irregularly shaped pavers in a seemingly haphazard way to create a distinctive, natural, and vintage aesthetic. To lay crazy paving, one must embrace the irregularity and let the pieces fall into place organically. This technique originated from Ancient Rome, lending it a time-honored pedigree that adds to its charm. Imagine adding a touch of Roman grandeur to your garden!

Crazy paving not only allows you to create a unique style, it also offers versatility and an opportunity for creative expression. You can use this method to enhance various outdoor spaces, including driveways, patios, and courtyards. It’s a great DIY project that allows you to let your creativity run wild as you arrange paving stones in your own unique pattern. You can choose from a variety of natural stones such as bluestone, limestone, marble, slate, quartz, and porphyry, each offering its own unique texture and colour.

Benefits of Crazy Paving

Durability stands out as a key advantage of crazy paving. The use of non-rectangular natural stone or concrete paving, which is naturally irregular in shape or broken, enhances the durability and adaptability of the design. This makes it a resilient choice capable of withstanding various weather conditions and heavy traffic.

Crazy paving goes beyond mere durability and versatility; it’s an avenue for crafting visually striking and organic designs. The irregularly shaped stones used in crazy paving create distinctive patterns that add a naturalistic appeal to your outdoor space. Moreover, the cost of crazy paving can vary from $5 to $40 per square foot, making it a financially viable choice depending on the materials chosen and the intricacy of the design.

Preparing the Area for Crazy Paving

Proper preparation of the area is a prerequisite before you start your crazy paving project. This involves excavation, securing the area, and creating a solid base. Such preparation is vital for achieving a robust and enduring pavement capable of withstanding diverse weather conditions and continuous use.

Here are the specific steps to prepare your space for a masterpiece of crazy paving.

Excavation and Securing the Area

The first step in your crazy paving journey involves marking the designated area for your pavement. Grab a shovel and delineate the edges of the path. Then, measure both sides to determine the lengths of garden edging needed. This process is particularly enjoyable for DIY enthusiasts who love getting their hands dirty.

Next, you need to excavate the area. The recommended depth of excavation for crazy paving is up to 200mm to ensure a strong base for stability. During the excavation process, make sure to remove any vegetation from the area. This can be done manually or using weeding tools for hard-to-reach areas. Once the upper part of the weeds is removed, apply a vinegar solution made of equal parts water and vinegar to eradicate the roots.

Creating a Solid Base

Establishing a solid base is necessary for a sturdy foundation for your crazy paving, preventing movement and providing durability to support the weight and traffic it will encounter. Typically, it is recommended to use a concrete slab for laying crazy paving, but in some cases, a thick base of sand can also be used.

The recommended thickness of the base depends on the intended use of the area. Here are some guidelines:

  • For laying driveways or forecourts, a 100mm thick bed of C20 concrete is recommended.
  • For areas like patios or other applications that don’t bear much weight, a bedding mix of 10:1 and a thickness of 50mm is suitable.
  • .
  • For heavier applications, a thicker bed may be necessary.

Gravel also plays a significant role in establishing a sturdy and long-lasting base on the prepared surface.

Laying Crazy Pavers: A Step-by-Step Guide

With the area prepared, we can now delve into the thrilling task of how to lay crazy pavers. This involves selecting and preparing your pavers, arranging and positioning them, and adhering and grouting them for a finished look.

Prepare yourself as we embark on this creative journey!

Selecting and Preparing Your Pavers

The first step in laying your crazy pavers is selecting the right material. As mentioned earlier, you can choose from a variety of materials such as:

  • Bluestone
  • Sandstone
  • Quartz
  • Limestone
  • Marble
  • Slate

Each of these materials offers its own unique texture and colour, adding to the versatility of your crazy paving design with random shapes.

Once you have chosen your material, the next step is to break or cut them into irregular shapes. This is what gives crazy paving its distinctive look. For precision, you can use a stone cutter or chisel. Alternatively, you can place the paving pieces over an old towel and gently tap them with a hammer or a rubber mallet to achieve the desired size and shape.

After that, categorise your pavers based on their size and colour. This will help you achieve a well-proportioned distribution of sizes and colour tones across the paving.

Arranging and Positioning Your Pavers

The real fun begins with arranging and positioning your pavers. This is when you get to see your design come to life. The aim here is to maintain an organic and unstructured look while avoiding uniformity and predictable patterns. Start by laying out your pavers in a visually appealing pattern, ensuring consistent gaps.

To ensure a successful crazy paving project, we recommend laying the stones while avoiding certain common mistakes, such as:

  • Laying stones in straight lines
  • Neglecting to create borders
  • Backfilling with dirt
  • Laying a shallow base
  • Not compacting the base
  • Improper bedding sand installation

These errors can compromise the effectiveness and beauty of your crazy paving.

Adhering and Grouting Your Pavers

The final step in laying your crazy pavers is adhering and grouting them. Whether you’re using a flexible glue or sand-cement mix depends on the base, but the goal is to ensure a durable and attractive finish. Here’s how to do it:

  1. Prepare your grout mixture.
  2. Apply the grout with a rubber float to fill the gaps between the pavers.
  3. Use a damp sponge to remove any excess grout and create a clean finish.

It’s recommended to use Ardex WJ50 grout due to its suitability and resilience for crazy paving. Also, consider using a darker mortar as opposed to plain mortar during jointing. This can significantly improve the overall aesthetic of your crazy paving. To establish a robust bond, meticulously pack the mortar into the joint to eliminate any voids, and incorporate a strengthening additive such as SBR into the Class II mortar mix.

Styling Your Crazy Paved Outdoor Space

Styling plays an equally crucial role as stone and grout in your crazy paved outdoor space. When selecting furniture, choose pieces that complement the rustic and natural aesthetic of your space. Wooden or wicker furniture integrates seamlessly with the irregular shapes and textures of crazy paving, creating a harmonious and welcoming ambiance.

Selecting appropriate plants for your crazy paved outdoor space also plays a significant role. Consider:

  • Mixing and matching tones
  • Combining pavers with groundcovers
  • Incorporating vertical interest
  • Utilising containers

Choose low-maintenance plants that are well-suited to your local climate, and don’t forget about lighting. Adding pathway lights, rope lights, and hanging outdoor lights such as fairy lights can enhance your space and establish a captivating evening ambiance.

Maintenance Tips for Crazy Paving

Proper maintenance of your crazy paving ensures its aesthetic appeal and longevity. Regular cleaning with a high-pressure washer combined with stone cleaning detergent is recommended. Avoid using acidic cleaners as they can harm the surface of the pavers.

Sealing is another important aspect of maintaining your crazy paving. It is recommended to pre-seal the pavers, especially those with split finishes, using a penetrating sealer like Aqua Mix – Pro Block. This preserves the natural appearance of the stones and retains slip resistance, making it easier to clean and safeguarding the stone from stains. It’s advisable to reseal outdoor exposed areas every 8 years to maintain their protection.


In conclusion, crazy paving is a unique, versatile, and creative way to enhance your outdoor space. Its durability, aesthetic appeal, and cost-effectiveness make it an excellent choice for homeowners seeking to inject a touch of vintage charm into their garden or patio. With the right preparation, material selection, and maintenance, you can create a stunning crazy paved space that will stand the test of time. So why not take up the trowel and embark on your crazy paving journey today?
